Answer:
Evolutionary relationships between different species of animals are best determined by Amount of common DNA sequence
Step-by-step explanation:
The exact way to find out the evolutionary relationship among two animals is by examining their DNA or protein sequences of shared genes. Explanation of which can be given with help of the DNA or protein sequences of shared genes. Biochemical evidences are very accurate in finding out the relationship between two organisms.
So, amount of common DNA sequence is used to find out evolutionary relationships between different species of animals.
